What is Systematise
(Seiton)?

Systematise is a study of efficiency. It is a question of how quickly you can
get the things you need and how quickly you can put them away. Just making an
arbitrary decision on where things go is not going to make you any faster.
Instead, you have to analyse why getting things out
and putting them away takes so long. You have to study this for both the people
using the things frequently and those who seldom use them. You have to devise a
system that everyone can understand.
